  <h3>What does this do?</h3>
  <p>Displays the stylesheet link and metadata for this page. Both global metdata from the global settings page and metadata for each page will be shown.</p>
  <h3>How do I use it?</h3>
  <p>Just insert the tag into your template like: <code>{header}</code></p>
  <h3>What parameters does it take?</h3>
  <ul>
    <li><em>(optional)</em>name - Instead of getting all stylesheets for the given page, it will only get one spefically named one, whether it's attached to the current template or not.</li>
    <li><em>(optional)</em>media - If name is defined, this allows you set a different media type for that stylesheet.</li>
    <li><em>(optional)</em>showbase (true/false) - If set to false, the base tag will not be sent to the browser.  Defaults to true if use_hierarchy is set to true in config.php.</li>
    <li><em>(optional)</em>assign - Assign the output to a smarty variable named in assign instead of outputting it directly.</li>
  </ul>
